1引言如何將地球空間信息通過一種數(shù)據(jù)交換表現(xiàn)在平面中国产又黄又爽又色视频在线，是地圖投影研究的范疇久久免费AV片国产精品。

Furthermore the computer implementation process and some key topics including map projection system, map projection parameters, algorithm optimization and error computation and control in the transformation process are discussed in this paper.

以此為基礎(chǔ)，具體探討了地圖投影變換計(jì)算機(jī)實(shí)現(xiàn)的主要過程熟妇操B，討論了地圖投影體系日本高清wwwcom、投影參數(shù)、算法優(yōu)化和誤差控制等投影變換計(jì)算機(jī)實(shí)現(xiàn)中的關(guān)鍵問題

由子午線形成四邊形并且把地球上的領(lǐng)域相應(yīng)的投射在地圖上形成的地圖投影圖www.淫荡网。

As mentioned Live/Google maps use a Mercator projection, but although their datum is based on WGS84, they use a sphere instead of an ellipsoid.

上文所說Live Map / Google Map 使用墨卡托投影欧美丰满熟妇性XXXX动图，但雖然他們的大地基準(zhǔn)應(yīng)該是基于WGS84的，他們用球體模型替換了橢球體模型sese96。

Many analysis technology and space data are designed by the two-dimensional coordinates or plane coordinate, and used plain map projection methods to storage space coordinates, so many times we all need three-dimensional map projection to convert 3D geographical coordinates into the plane coordinates.

許多分析技術(shù)和空間數(shù)據(jù)都是針對二維坐標(biāo)或平面坐標(biāo)設(shè)計(jì)啊啊啊用力插好舒服国产视频，以平面地圖投影的方式來存儲(chǔ)空間坐標(biāo)，因此很多時(shí)候我們都需要利用地圖投影將三維的地理坐標(biāo)轉(zhuǎn)換為平面坐標(biāo)一级国产。

Mercator is the type of projection you see used on Live maps and Google maps, but as many often mistakenly thinks, they do NOT use WGS84 for the projected map, although WGS84 is used when you directly input longitude/latitude values using their API.

Live Map和Google Map都使用墨卡托投影，但并不像人們認(rèn)為的那樣他們使用WGS84基準(zhǔn)面一级黄色片不卡，雖然你在他們的API中輸入的值是WGS84下的值欧美一级黄色大片网址。【譯注：原因是WGS84基準(zhǔn)面是基于橢球面的色色影视网站，而LiveMap和GoogleMap使用的是球面黃色A片一级一级一级。另外，YahooMap使用的是等距圓柱投影国产高潮动漫在线观看免费视频。
